We have a Viszla and no children. He gets “ultra-premium” dog food, ridiculous toys, and relatively expensive treats (because he likes them better!) When we were deciding on a vet, we picked the place run by people with degrees from Cornell, because we looked it up and Cornell is the top-ranked vet school. I'm pretty sure we're not economizing. And I'm pretty sure Robin Hanson's on the right track. But it is possible to call around and get accurate quotes on the cost of neutering your dog. I didn't happen to call around because Winston gets the very best! (Also, I figured prices wouldn't vary that much in a competitive market.) I don't think Winston is impressed, but we're pretty happy with ourselves.
